WASHBOILER.

" Application led October 22, 1923. Serial No. 670,646.

To ali whom it may concern.'

Be it known that ADAM E. FISHER, a citizen of the United States, residing at St. Louis and State of Missouri, has invented certain new and useful Improvements in ivashboilers, of which the following is a sjiwciiieation. l

This invention is an in'iprovement upon a certain type of pcrcolating or liushing clothes washing machine or device, as shown in United States Letters Patent No. 1,423,- 9123 of July 25, 1922, to John T. Nood onI wash boiler attachments. Clothes washing devices of this type are provided with a steam forming chamber in some part of the structure, usually at the bottom for positioning within an ordinary boiler immediatcly over the fire, and with perforated tubes leading from this chamber, through which hot water and steam are forced by the action of the expanding steamy formed in the steam chamber. This type of washer is very etlicient for washing clothes, and it follows that the quicker the water in the boiler is heated and the stronger the streams of water from the perforated tubes, the more efiicient is the machine. It is the purpose of this improvement, therefore, to provide simple and effective means for accelerating the heating of the water in the boiler and projecting the streams of hot water out through the said tubes with greater force.

ln the drawing Figure 1 is a bottom view of a clothes washing device of the type referred to, having this kimprovement incorporated'there- Figure 2 is a vertical, longitudinal section through the clothes washing device, having this improvement embodied, the device being positioned upon the bottom of an ordinary clothes wash boiler;

Figure 3 is a detail of a set of the spiral channel strips detached from the washer;

1Figure 4l is a detail of one of the spirally beaded or grooved percolating tubes.

This invention is an improvement upon the clothes washing device 1 of the type hereinbefore referred to, and which includes the steam forming chamber 2 at the bottom thereof adapted for positioning upon the bottom of an ordinary wash boiler 3, the boiler bottom serving as a closure for the chamber 2 at the lower side and so completing the chamber. The device 1 is provided with `conventional tubes 4i leading from the chamber 2 and these tubes are perforated with a plurality of lateral holes 5 through which the hot water streams and percolates under the action of the steam formed in the chamber 2, in a well known mann er.

ln the use of such a washing apparatus, the water in the boiler 3 must of course be first heated to the boiling point in order to form steam in the chamber 2, and this heating process is relatively slow because of the fact that the water is heated in bulk. After the formation of steam, the hot water is driven up through the tubes 4, out through the holes 5, and then falls and flows back again under the edges and through the open corners of the base into and through the chamber 2, in constant circulation.

lt is well known that definite direction impart-ed to the movement of a body of water in the process of heating, and fencing the water being immediately subjected to the action of the heat from the mass of the water, as through a coil of pipe, greatly expedites the heating as against heating the water in bulk form. It is also thought that a rotary motion imparted to a stream of water passing through a tube or the like, accelerates the passage. l

This improvement, therefore, consists in means for fencing the water to circular channels and imparting a rotary motion to it as it passes through the steam forming chamber 2 and up through the tubes 4r. This object is accomplished by mounting within the steam forming chamber 2, spiral channel strips 6 and 7, with their inner ends disposed adjacent the openings 8 into the tubes 4, and their outer ends being flared and extended straight and disposed outwardly adjacent the sides or corners of the chamber 2. hile two spiral channel strips are here shown arranged at each end of the chamber 2, more or less may be employed as desired, the same being arranged in inter-coiled and substantially parallel relation as shown, and leading out to different points adjacent the sides of the chamber 2. In any conventional manner of fastening, as by soldering, the spiral strips 6 may be secured edgewise within the chamber 2, perpendicularly to the under side of the top plate 9 of the chamber, and these strips are of a width or height approximately equal to the width or height of the sides 10 of the chamber 2, .so that when the device is seated within and upon the bottom of the boiler 3, completely enclosed spiral Water channels 1l are formed for leadingthe Water through the chamber 2 into the tubes t. ln order to accentuate or continue the rotary motion of the Water in passing through the tubes l., the said tubes may be formed Wit-li spiral beads, grooves or bosses l2 running,I from bottom to top, after the manner ot' the riiing of a gun barrel.

ln actual use, it is found that the arrangement described both facilitates the heating Ot' the Water and greatly auginents the force and action ot the Water streaming` through 1the tr-bes and holes of the Washing device. Ot cou 1 the percolating element could be soldered permanent-ly Within the boiler if desired; and While l have herein described Certain specific manner and method of cofzstructing` and assembling` the elements of my invention, it is understood that I may vary from the same in minor details, not departing from the spirit of my invention, so as best to construct a practical device for the purpose intended, as defined in the appended claims.

I claim:

VIn a clothes washing device embodying 'flat basal steam forming chambers having,` pcrcolating` tubes rising therefrom; a plurality of channel strips mounted edgeivise and spirally intercoiled in substantially parallel relation Within the basal chamber beneath each tube, the outer ends of the strips being separated and flared straight towards separate corners ot each basal chamber and the inner ends being spirally directed towards the base of the percolating tube.

in testimony whereof l aix my signature.
